I've lately been thinking it's unnatural based on all the hormones now in milk. Think of it as well that cow's are eating grass, which has prolly been spayed with pesticides. This will get concentrated in it's milk. Same thing goes with humans. When a mother drinks alcohol, it's transfered to the baby via the milk.
I think I saw somewhere that human breastmilk can sometimes be classified as a toxic substance for this very reason. Pesticides and other chemicals are highly concentrated in fatty tissue, and the higher up the food chain you are, the more concentrated it gets in you.
There must be only few women in the world who could describe their breast milk as organic.
We only buy organic milk for breakfast and other uses.
The World Health Organization recommends infants drink mother's milk for one to two years as it contains many antibiotics and nutrients needed for kids to properly grow. After this time, milk (human or cow) isn't needed. There are plenty of other ways to get your calcium than milk.
Yes, I think the WHO recommends 1 year as the MINIMUM amount of time to breastfeed. In Finland and other Scandinavia countries, something like 90% of mothers breastfeed this long. In the UK, it's about 6%.
My partner breastfed our daughter up to about 2 and a half. (along with her eating normal babyfood at the standard ages) Our daughter tapered off and stopped when she felt like it, at a time of her own choosing.
We have friends who want to do the same, but can't cos of work, social expectations, and other pressures. Scandinavia made a big effort at addressing these pressures, which is why they have such a high percentage.
